[0023] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] like Figure 1-Figure 3 As shown, an automatic feeding positioning riveting device comprises an upper part feeding assembly 1, a lower part feeding assembly 2, a lower part positioning assembly and a blanking riveting assembly; the upper part feeding assembly 1 comprises an upper flow channel 11 and a guide blanking plate 12, and an upper part 13 slides from the upper flow channel 11 to the guide blanking plate 12 to be in place; the lower part feeding assembly 2 comprises a lower flow channel 21, a push plate 22 and a power source 3, the push plate 22 is fixedly arranged below the lower flow channel 21, and the lower part 23 slides from the lower flow channel 21 to the push plate 22, and the power source 3 drives the lower part 23 to move on the push plate 22;

[0025] like Figure 1 As shown, the lower part positioning assembly includes an ejector assembly 4, a lower die 5 and a power source 2. The lower die 5 is located directly below the guide blanking plate 12 and is installed on the ejector assembly 4. The power source 1 3 drives the lower part 23 from the push plate 22 to the lower die 5. The ejector assembly 4 is connected to the power source 2. The power source 2 drives the ejector assembly 4 to move up and down and then drives the lower die 5 to move in the vertical direction.

[0026] like Figure 1-3 As shown, the blanking and riveting assembly includes an upper die 7, a riveting motor and a transfer bracket 8. The upper die 7 is located directly above the lower die 5. The riveting motor drives the upper die 7 to move downward. The transfer bracket 8 can drive the guide blanking plate 12 to separate to the left and right so that the upper part 13 falls to the surface of the product to be processed before contacting the upper die 7 and is accurately inserted into the lower die 5 under the guidance of the guide blanking plate 12. The riveting motor continues to drive the upper die 7 downward so that the upper part 13, the lower part 23 and the product are riveted together.

[0027] like Figure 1 and Figure 2 As shown, the ejection assembly 4 includes an ejection wedge 41, a guide plate 42, a bearing shaft 43 and an ejection rod 44. The bearing shaft 43 is placed on the ejection wedge 41. The guide plate 42 constrains the bearing shaft 43 to move only in the vertical direction. One end of the ejection wedge 41 is connected to a second power source. The second power source drives the ejection wedge 41 to move horizontally and then drives the bearing shaft 43 to move in the vertical direction. The lower end of the ejection rod 44 is installed on the bearing shaft 43 through a bearing. The lower mold 5 is installed on the top of the ejection rod 44 and is located on one side of the push plate 22.

[0028] like Figure 2 As shown, at high speed, a servo motor or a stepper motor is used as the power source 1 3 and the power source 2. At this time, the power source 1 3 includes a gear 31, a push rod 32, an upper rack 33 and a motor. The motor drives the gear 31 to rotate. The upper rack 33 is engaged with the gear 31 and can move horizontally under the rotation of the gear 31. The upper rack 33 is connected to the push rod 32. The push rod 32 pushes the lower part 23 from the push plate 22 to the lower mold 5 under the rotation of the gear 31. The power source 2 is the lower rack 6. The lower rack 6 is engaged with the gear 31 and can move horizontally in the opposite direction to the upper rack 33 under the rotation of the gear 31. The lower rack 6 is connected to one end of the ejection wedge 41. The lower rack 6 drives the lower mold 5 to move up and down by pushing the ejection wedge 41 under the rotation of the gear 31.

[0029] When the speed requirement is not high, the power source 1 3 and the power source 2 are cylinders.

[0030] like Figure 1 and Figure 3 As shown, the blanking riveting assembly also includes a transfer sleeve 9, the upper end of which is connected to the riveting motor rod, and the lower end is connected to the upper die 7, and the lower part of the transfer sleeve 9 is an inverted conical slope. The transfer bracket 8 includes a bracket 81 and a transfer assembly 82 mounted on the bracket 81 and symmetrically located on both sides of the lower die, and the transfer assembly 82 includes a spring 821, a bearing rod 822, a roller 823 and a baffle 824. One end of the bearing rod 822 is mounted on the bracket 81 through the spring 821, and the other end is mounted with a roller 823. The bottom of the bearing rod 822 is connected to a baffle 824, and the baffle 824 is connected to the outer wall of the guide blanking plate 12. When the riveting motor drives the transfer sleeve 9 to move downward, the roller 823 contacts the lower part of the transfer sleeve 9 and separates left and right under the pressure of the inverted conical slope of the transfer sleeve 9 and drives the two baffles 824 to separate.

[0031] The specific working principle of the above technical solution is as follows: first, the lower part 23 and the upper part 13 fall into the lower runner 21 and the upper runner 11, and the upper part 13 slides into the guide blanking plate 12 to be in place. Then, after the lower part 23 falls into the push plate 22, the motor drives the gear 31 to rotate clockwise, the upper rack 33 moves forward to drive the push rod 32 forward, and the lower rack 6 drives the ejection wedge 41 to retreat; when a cylinder is used in this process, the cylinder is used to replace the push rod 32 and the lower rack 6. Next, the bearing shaft 43 falls into place under the guidance of the guide plate 42, and the ejection rod 44 and the lower mold 5 fall into place, and the lower part 23 enters the lower mold 5 under the push of the push rod 32, and then the upper rack 33 drives the push rod 32 to retreat again, and the lower rack 6 drives the ejection wedge 41 to move forward, and the ejection wedge 41 pushes against the bearing shaft 43 and drives the ejection rod 44 and the lower mold 5 to be ejected upward to be in place.

[0032] After the upper and lower parts are in place, the upper die 7 and the transfer sleeve 9 move downward driven by the riveting motor rod. Before the upper die 7 touches the upper part 13, the transfer sleeve 9 contacts the rollers 823 on the left and right transfer brackets 8. The left and right bearing rods 822 separate left and right under the downward pressure of the inverted conical slope of the transfer sleeve 9 and drive the left and right baffles 824 to separate. The upper part 13 falls before the upper die 7 contacts it, falls onto the surface of the product to be processed, and is accurately inserted into the protrusion of the lower die 5 under the guidance of the guide blanking plate 12. As the riveting motor rod continues to move downward, the upper part 13 and the lower part 23 are riveted together with the product under the downward pressure of the upper die 7, and a working cycle is completed.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications of the above assumptions should also be regarded as the scope of protection of the present invention.
